The DIDCSU front panel's System LED (SYS) is green when the
module has passed the power-up self-test.
The panel also contains four status LEDs:
• Two for network port status
• Two for data port status
Chapters 3 and 4 of this manual define the LEDs and alarms for the
T1 and E1 versions respectively.
Three front panel management ports support management of the
local node.
• LOCAL —6-wide modular, direct connection to the Craft
interface using an ASCII terminal or a PC running a terminal
emulator
• PRI —8-wide modular, RS-232-compliant Primary Management.
Used for ACP bus extension between shelves in a multi-shelf
node.
• EXT—8-wide modular, RS-232-compliant port for daisy-
chaining multiple AS2000 shelves (ACP-managed modules
only).
Rear connector interface modules (CIMs) provide network ports for
connection to the wide area network facility and data ports for
connection to synchronous serial data terminal equipment (DTE).
They also provide the following connections:
• Alarm relay—These contacts can be wired to external alarm
equipment. The connector pins provide output as a normally
open (NO) contact, or a normally closed (NC) contact.
